Morning Poll: Who Should Play John McCain in Upcoming Flick About 2008 Presidential Campaign?

As we mentioned yesterday, HBO's making a movie based on John Heilemann and Mark Halperin's bestselling book, Game Change, in which the authors air some of the McCain campaign's dirty laundry -- namely, Sarah Palin and her continual battles with campaign staffers.

The role of Palin will be played by Julianne Moore, but the role of McCain has not been cast.

One potential faux-"Mav" is Robert Duvall, who stumped for McCain in New Mexico during the 2008 election.

Another possibility would be Steve Martin, who according to People's entertainment staff, "could bring a sense of humor to the role. And any political race where a guy named Joe the Plumber becomes an overnight sensation deserves a the comedy treatment."
